2019 Chevrolet Tahoe engine problems

Filed Oct 21, 2026 · Engine · TX

At approximately 80,700 miles, I started my 2019 Chevrolet Tahoe (6.2L V8) to take my family on errands. My wife heard a squeaking noise from the engine as she walked to the vehicle, and I got out and heard the same noise. No warning lights or messages appeared on the dashboard, before or after. I took the vehicle to an independent repair shop, expecting a belt problem. After inspection, the shop told me the valve lifters had failed and needed replacement, and that the camshaft would likely need replacement as well. I declined the repair and took the vehicle to a GM dealership for inspection and documentation. The GM dealer confirmed the lifters need replacement. They could not confirm whether the camshaft is also damaged without an engine tear down, which I have not authorized. The dealer estimated $13,200 to replace the lifters and camshaft. The independent shop estimated $8,200. The vehicle has not been repaired, and the failed components are still in the engine and available for inspection. I am concerned for my family’s safety. Lifter failure on this engine can cause misfires, loss of power or engine failure while driving. We use this vehicle to transport our family, and a sudden loss of power on the road could cause a crash.

There was no accident, but while I was on a busy highway, my vehicle started failing me. I wasn’t able to go past 50mph. After taking it to the dealership they said it’s a torque converter and transmission failure.

6.2l Engine Failure: Vehicle was purchased last November at 113000 miles and at approximately 127000 miles we heard a noise coming from our engine one morning. Took it to the dealer we purchased the truck from because we bought an extended warranty and they got back to us and said there were metal flakes in our oil. They dove deeper and said it was connected to internal engine failure. They told us we could keep driving it but we said no that’s too dangerous and current it’s sat 3 weeks on their lot while we figure out what the warranty company is going to do and if we’re going to be able to get a new motor from GM. I owe $40,000 on a car that is basically junk and idk what to do. When my dealer told me GM only put 21-24 in their recall I started digging and found out the entire L87 6.2 gas platform is plagued. Please be informed that my maintenance records are also intact with regular scheduled oil changes performed by professionals. Please help!
